Almost all of the rock that we have on Earth today is made of the same
stuff as the rocks that dinosaurs and other ancient life forms walked,
crawled or swam over. While the stuff that rocks are made from has stayed
the same, the rocks themselves, have not. Over time rocks are recycled
into other rocks. Moving tectonic
plates are responsible for destroying and forming many different types
of rocks.
